POLi SHlNG COMPOUND.

SPECIFICATION forming art of Letters w s No. 667,008, amen January 29, 1901.

Application filed October :26, 1900. se um. 34,292. (No specimens.) I

and HENRY ADAMS, citizens of the United States, residing at Newark, in the county of Essex and State of New J ersey,.have invented certain new and useful Improvements in Polishing Odmpounds; and we do declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a polishing compound for polishing purposes generally, and more particularly for lacquered metal without removing the lacquer therefrom.

The invention consists of the following ingredients powdered white dextrine, powdered gum-tragacanth, aceticacid, hydrochloric acid, refined petroleum, oil of citronella, and distilled water.

To make one gallon of the preparation, we use, by weight, powdered white dextrine, four ounces; powdered gum-tragacanth, one and one-fourth ounces, and, bymeasure, acetic acid, four ounces; hydrochloric acid, onefourth of; an ounce; refined petroleum, sixtyfour ounces; oil of citronella, one ounce; distilled water, fifty-six ounces. To this may be added twenty grains of any desired pigment, such as rouge. In manufacturing the compound the four ounces of powdered dextrine, one and one-half ounces of gum-tragacanth, and the twenty grains of rouge are first triturated in a large Wedgwood mortar, and then nineteen ounces of .refincd petroleum and one ounce of citronella are thoroughly mixed with the mass and rubbed or stirred for five minutes, and then the acids are added to thirty two ounces of water, and this is added .to the mixture in the mortar gradually,

while continually stirring, until perfect emulsion is formed, and while still stirring the balance of the oil and water to make one gallon of the compound is gradually added. The specific gravity of the refined petroleum at59 Fahrenheit is 0.79 to.0.80. Thes'pecific renheitis 1.163. The specific gravity of the acetic acid at 59 Fahrenheit is1,04 1.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-" gravity .of the hydrochloric acid at- 59 Fah;

1. A polishing compound resulting from;

substantially the'proportions ,hferein statedzl powdered white de'xtrine', gum-tragacanth, acetic acid, hydrochloric acid, refined petrothe mixing of the following ingredients in leum, oil of citronella and distilled water,.

substantially as set forth.

2. A polishing compound resulting from the mixing of the following ingredients in" substantially the proportions herein stated: powdered white dextrine,powdered gurn-trag' acanth, acetic acid, hydrochloric acid, refined petroleum, oil of citronella, distilled-water, and a coloring-pigment, substantially as set forth.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses. l I
